Hi!
The kernel package currently fails to build from source on sh4 since
the build scripts try to pass the '-m32' compiler option on gcc which
is not available with gcc on sh4 (also according to the manpage).
Selecting HAVE_C_RECORDMCOUNT in arch/sh/Kconfig (see attached patch
by Ben Hutchings) fixes the issues. However, I also suggest removing
the line $cc .= -m32; for sh compiler options in scripts/
recordmcount.pl.
Steven and SH experts, what do you think of this?
It seems most compilers don't support -m32, unless they're biarch.

Adrian, can you check whether ftrace seems to work on the kernel built with HAVE_C_RECORDMCOUNT selected? (See Documentation/trace/ftrace.txt and particularly the 'function' example.) I guess that involves also installing the kernel and running it? The reason why I ask is that I currently don't have physical access to any of the SH4 machines yet as I am still waiting for Nobuhiro Iwamatsu to send me one of the spare boards he has. Thus, if the kernel locks up the kernel for whatever reason, I am a bit lost until Nobuhiro can reset the machine. Having my own local SH4 machine would simplify things dramatically.
